CARL OBERLANDER, OF ARASTRA, COLORADO.

WINDMILLPOWER.

SPECIFICATION forming part of Letters Patent No. 691,1 68, dated January 14, 11902.

Application filed September 12, 1901. Serial No. 75,176. (No model.)

To all 'wh/071e it may concern;

Be it known that I, CARL OBERLANDER, a citizen of the United States, and a resident of Arastra, in the county of San Juan and State of Colorado, have invented a new and im# proved Windmill-Power, of which the following is a full, clear, and exa-ct description.

This invention relates to improvements in windmill power or mechanism; and the ob- Io ject is to provide a power of this description my invention, and then point out the novel featuresin the appended claims.

Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indi- 2o cate corresponding parts in all the figures.

Figure 1 is a sectional elevation of a windmill-power embodying my invention. Fig. 2 is a vertical section at right angles to Fig. l and on the line 2 2 of Fig. 3. Fig. 3 is a top z5 plan view, and Fig. 4 is a plan View partlyin section.

Referring to the drawings, 5 designates the tower of the usual construction, and mounted on the tower is the turn-table 6. The wind- 3o wheel7is mounted on a shaft 8, havingbearings in boxes secured to the turn-table, and arranged in the shaft 8 are the cranks 9 and 10. From the crank 9 a link 11 extends to a connection with a cross-head 12, arranged to 3 5 slide in guides 13, extended upward from the turn-table, and this cross-head is connected to a 'tubular operating-rod 14, which has a bearing in a sleeve 15, attached to the turntable. vExtended from a pin on the lower end 4o of the operating-rod 14 is a link 16, which at the lower end engages with the crank 17 of a crank-shaft 1S, from which power is imparted to machinery to be driven. This shaft 18 has bearings in cross-bars attached to the tower,

45 and on the shaft is a sprocket-wheel 19, having a chain engagement 2O with a sprocketwheel 21 on a counter-shaft 22, provided with a band-wheel 23. From the crank 10 of the shaft 8 a link 24 extends to and is connected '5o with the pin on a crosshead 25, moving in the guides 13 and connected to a supplemental power-rod 26, which is movable through the tubular rod 14, and connected to the lower end of the rod 26 is a cross-head 27, from which a link 28 extends to a connection with a crank 29 on the shaft lS. The cranks 17 and 29 arc arranged in -opposite directions, as are also the cranks 9 and 10,` and therefore it is obvious when the shaft 8 is rotated the rods 14 and 26 will be operated in opposite directions for alternately operating the driving-shaft 1S, and therefore lost motion is overcome.

I will now describe a means for throwing the wheel into and out of the wind. Mounted to swing horizontally with relation to the turn-table is a frame 30, forming a portion of the vane rod. The lower member of this frame 30has pivotal connection with the turntable, while the Lipper member of the frame has pivotal connection with a standard 31 on the turn-table. At one side the frame 30 has toggle-link connections 32 33 with the turntable, the links being connectedy by a pivot 32, and at the opposite side it has togglelink connections 34 35 with the turn-table, the said links being pivoted together at 35a. The links 32 and 34 engage with thesame pivot 34 on the frame 30. the link 35 is connected to a rock-shaft 36, having bearings in boxes secured to the standard 3l, and the upper end of this rock-shaft 36 has link connections with the operatingrod 26. As here shown, a lever 37 is rigidly connected to the upper end of the shaft 36, and from this lever 37 a link 3S extends tocan arm 39, which connects with the rod 26. The rod 26 is designed to be rotated by a movement ofthe arm 39; but said rod is also designed tofmove vertically through said arm. To permit these movements, the rod at its portion passing through the arm is made angular in cross-section. The lower portion of the rod 26 is designed to rotate in the crosshead 27. It is pro vided with an annular chan nel, into which pins attached to the crosshead extend, as clearly shown in Fig. 1. Below the'cross-head 27 the said rod 26 is made angular in cross-section and engages in the hub portion of a miter-gear 40, which is supported in a cross-bar 4l,attached to the tower. The miter-gear 40 meshes with a miter-gear 42 on a shaft 43, attached to the outer end of which is a sprocket-wheel 44, having a chain connection 45 with a sprocket-wheel 46, at

The inner end ofv A' tached to a shaft 47 at the base of the tower. On this shaft-47 is a hand-wheel 48. tating the shaft 47 the vane may be thrown into and out of the wind-that is, by rotating v the said shaft in one direction the chain-gearing and the ruiter-gearing will rotate the rod 26, which through the link connections will rock the rock-shaft 36,and consequently move the frame 30, carrying the vane to operative position, as indicated in Fig. 3. By rotating thel shaft 4'7 'in the opposite direction the frame carrying the vane will be moved to the position indicated in Fig. 4, and thu's carry the wind-wheel out of operative position.

To prevent undue shock or strain, thelinks 32 33 are connected to the links 34 35 by means of a spring 49, and to limit the movement of the frame toward its inoperative position a stop-finger 50, attached to the link 32, is designed to engage with an angle-arm 5l, attached to the rock-shaft 36, and a pin extends from the link 35 into a slot in said angle-arm 51.

Having thus ydescribed my invention, I claim as new and desire to'secure by Letters Patentl. In a windmill-power, a tower, a turn-table on the tower, a windmill-shaft mounted on the turn-table and having two cranks, a tubular operating-rod having connection with one of the cranks,a supplemental operatingf rodv extended through the tubular rod and l' having connection with the other crank, a double crank-shaftwith which the lower ends of said rods connect, a vane-carrying frame mounted to swing, and connections between is o said frame and the supplemental rod, wherevby the frame may be swung substantially as specitied.

2.' In a windmill-power, a tower, a turn-table on the tower, a wheel-shaft supported on vthe ,turn-table and having two cranks, oper- `ating-rods connecting with -said cranks, one of said rods having a rotary motion, means operated from the base of the tower for causing said rotary motion, a vane-carrying frame mounted to swing relatively to the turn-table, and connections between said frame and the said rotary shaft, whereby theframe may be turned or deected,s'ubstantially as specified.

3. In a windmill-power, a tower, a turn-ta- By roble on the tower, a double crank-shaft mounted on the tu rn-table,a tubular operating-shaft movable through the turn-table, a link connection between said tubular shaft and one of the cranks of the crankshaft, an auxiliary operating-rod movable through the tubular rod, a link connection between said auxiliary v rod and the other crank of the crank-shaft, a crank-shaft supported in the tower below the turn-table, connections between the operating-rods and the cranks of said last-named crank-shaft, a counter-shaft supported in the tower, and driving connections between the yas speciied. Y

5. In a windmill-power, a tower, a turn-table on the tower, a wind-wheel shaft supported on the turn-table, operating-rods having connection with said shaft,one rod being movable in the other,a vane-carryingframe mounted to swing on a horizontal plane, a vertical rock-shaft, an arm extended from the inner of said operating-rods and through which said rod is movable,link connections between said arm and the rock-shaft, link connections between said rock-shaft and the vane-carrying frame, link connections at the opposite side between said frame and the turn-table, a spring connecting the opposite links, a stoptinger carried by a link of one side, and an angular stop-arm attached to the rock-shaft, substantially as specified.

In'testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.

CARL OBERLANDER.
